This game is teaching kids the bases of fractions. Inspired by the popular video game Street Fighter, Fierce Ninjas is a fast pace fighting game with lots of learning. It has a 2D feel that you and your friends will enjoy. The fighting system is very entertaining and solid. I believe you will always come back for more. This game challenges the mind in many ways. Let me tell you a little bid about this game. Each player must take turns drawing from the battle cards deck. When a player in his or her turn has drawn a card from the battle deck, each player must look to see what it shows. For each attack points each player receives; each player must write the appropriate fraction that corresponds to his or her grid. If you don’t have the fraction of 20/20 before your opposing player, you win the game. (Note) if you get this game, please cut these items out and place them on cardboard; or laminate them. It's up to you. I hope you have a great time playing this game.
